The word lullaby has been in the English language since the Middle Ages - one of several, such as rockaby and hushaby, which show how generations of mothers and caretakers have helped their children fall asleep through music.

The gorse on the moor moans by your grave, the brackens grow green and tall and wither into dead gold year by year, the lake gleams gloomily in fitful flashes amid its borders of splendour; and you rest softly while the sea calls your lullaby nightly.
